    • Radiometric Data of Airborne Geophysical Surveys over the Eastern Adirondacks, New York State

    Metadata Updated: July 6, 2024

    Airborne geophysical surveys were conducted in the eastern Adirondacks from Dec. 7, 2015 - Dec. 21, 2015, by Goldak Airborne Surveys. The area was flown along a draped surface with a nominal survey height above ground of 200 meters. The flight line spacing was 250 meters for traverse lines and 2500 meters for control lines. Here we present downloadable radiometric (gamma spectrometry) data from those surveys as flight line data (csv format) or Geotiff images. Line data (EAdirondacksSpec.csv) are presented as comma separated values with the following definitions (see technical report for details): LINE Flight line number DATE YYYY/MM/DD TIME Time (UTM, 24-hour) hh:mm:ss LONG Longitude, WGS84 (degrees) LAT Latitude WGS84 (degrees) x_UTM18N Easting, UTM Zone 18N (meters) y_UTM18N Northing, UTM Zone 18N (meters) RALT Radar altimeter height (meters) BALT Barometric altimeter height (meters) GPSZ GPS elevation (meters) STPHT Standard temperature/pressure height (m) TEMP Temperature (degrees C) BARPRES Barometric pressure (kPa) TOTCT Raw total count (counts/second) COSFILT Low-pass filtered cosmic count (cps) RADON Computed radon background (cps) TC_DOSE Natural air absorbed dose rate (nGy/h) K_PCT Corrected potassium concentration (%) U_PPM Corrected uranium concentration (ppm) Th_PPM Corrected Thorium concentration (ppm) Geotiff images show potassium (K), equivalent uranium (eU), equivalent thorium (eTh), dose rate and a ternary diagram showing relative abundances of K, eU, and eTh. The files are, respectively, EAdirondacks_K.tif, EAdirondacks_eU.tif, EAdirondacks_eTh.tif, EAdirondacks_Dose.tif, and EAdirondacks_Ternary.tif. Images use projected coordinates (UTM 18N, WGS84); Geotiff tags are embedded. Colorbar images and a ternary legend are provided in separate files (DatasetName_colorbar.jpg, Ternary_legend.jpg).
